You should try using MSCONFIG in Windows XP to disable some of the unnecessary programs that automatically load on start-up. Disabling these programs will help your computer boot faster and crash less.
1. In Windows XP, go to Start > Run

2. Type MSCONFIG in the "Open:" box and then either press enter on your keyboard or click on the OK button.

3. This launches Microsoft's System Configuration Utility. Click on the Startup tab (the tab at the far right).

4. This takes you to a page with a list of "startup items." Startup items are programs that are automatically loaded every time you turn on your computer. Some startup programs are absolutely necessary, others are simply a waste of RAM.

Remember, disable only those programs that you recognize and don't need to have running all the time. When in doubt, leave it on.
5. Click on the OK button.
6. A message will pop up telling you that you must restart your computer before these changes will take effect. Click on "Yes" and your computer will automatically reboot.

7. That's it! Your computer should now boot faster and crash less.

The My Security Shield virus is a deadly virus. It can use temporary files to track your internet browsing, stealing private and sensitive data that you enter on various websites. This makes it absolutely essential to remove.

I would say the best type of program to remove this virus is anti malware software, such as Malware Bytes. However, it appears that you have already used this type of software to not great avail. I would suggest, if you haven't already, to try Malwarebytes. If you have tried this and it did not work, you can read about how to remove this virus here:

1. Reboot into safe mode with networking. If it does not work, continue anyway
2 .Open Internet Explorer, choose Tools menu and select Internet Options.
3. Click on the Connections tab and then on the LAN Settings button. Uncheck the checkbox labeled Use a proxy server for your LAN under the Proxy Server section and press OK.
4. Then start task manager or process explorer (http://technet.microsoft.com/en-us/sysin... ) and stop all processes that are like combination of random letters. If it fails, continue anyway, or check this guide : http://www.2-viruses.com/remove-my-secur... for more specific names
5. Start MSConfig and disable all startup entries that launch processes from within your user directory, for example App Data folder... You might need to reboot after this step, to safe mode with networking again.
6. Download good anti-malware tool like spyware doctor or malwarebytes. Scan with it, and delete stuff it finds (if it wont remove it itself).
7. Reboot.

I tried Giedrius M's method and it worked. Before that, I suffered the same like the asker. Just want to say 'Thank you so much!' The method was clear and easy to follow and the most important: it was effective. Great answer! Thank you!!
